Electron beam evaporation is that the membrane is put into the
water-cooled copper crucible, heated bydirect use of electron beam, the vaporized atoms or molecules of
membrane material is condensed to amould by incidence to the surface of the substrate after escaping
from the surface evaporation. Electronbeam evaporation has high thermal efficiency, beam density,
evaporation speed, high purity of film madethan the resistance heating evaporation.

Machine Introduction

The machine is controlled by industry touch screen and PLC and can
be manual controlled, half auto

controlled or auto controlled. Vacuum pumping, coating and gas
inflating is controlled by main controlling

box. The machine will alarm by sound and flashing light when the
cooling water and electric power supply

is cut off or the cooling water current is not enough for system
cooling. All pumps and valves have inter-
